    China was 3.2
  • the estimated infected persons were more than 30
    million

HCV infection in other target group
  • 6,052 females serving in amusement facilities,

  • Sex efficiency is low
  • MSM no higher risk than heterosexuals
  • to prevent HCV from sexual transmission can not
    be overlooked
  • Indicate that the general public in China may
    exist a dropped infection rate?

20
